Product is sintered, and then uses manual pressure or hydraulic press forced stripper mechanism.Product stripping is cumbersome, and graphite jig is easily damaged,
More, die cost height is taken in production process,
Conventional sintering mould, using overall graphite, product design is drawn out in inside, is sintered plus push-down head；Which
The drawbacks of be, product stripping is difficult, easily damages graphite inwall during the demoulding, and after the completion of sintering, mould inner wall does not allow easy to clean.
Utility model content
It is difficult to solve the said goods demoulding, easily damage graphite inwall during the demoulding, after the completion of sintering, mould inner wall is not allowed
The problem of easy to clean, the utility model patent provided a kind of pressure sintering graphite jig and supporting stripper apparatus.
A kind of pressure sintering graphite jig and supporting stripper apparatus, including graphite jig and stripper apparatus, described stone
Black mould includes graphite inner sleeve and graphite overcoat, and the outside of graphite inner sleeve is set on outside graphite；The graphite inner sleeve is two
Identical halfbody combines, and multiple cavities is provided with the graphite inner sleeve, cavity is built with sintered products, in graphite inner sleeve
Bottom, lowermost end cavity lower end installation graphite bolster plate, on the top of graphite inner sleeve, the cavity top of top is provided with upper pressure
Head.
Described stripper apparatus includes demoulding clamp and knockout pin, and described knockout pin front end is circular collar, and rear end is
Handle；The front end of the demoulding clamp is fixed plate, and external screw thread is carried on the knockout pin and is movably connected in by screw thread de-
On the female circular hole of band of die clamper rear end.
Further, graphite overcoat is annular, and graphite inner sleeve is round outside but spuare inside shape.
Preferably, the shape of the seaming chuck is identical with the shape of the cavity.
Further, described knockout pin is " work " font.
Further, the circular top loop diameter size is not less than the diameter dimension of seaming chuck and no more than outside graphite inner sleeve
The size of diameter.
Beneficial effect
The utility model is simple in construction, and function is easy, and graphite jig is divided into two parts of graphite inner sleeve and graphite overcoat,
Graphite inner sleeve uses isolation so that during product stripping, first inner sleeve and overcoat are separated, and then take inner sleeve apart, take out production
Product, the problem of successfully avoiding traditional moulds from bringing, the sintered products demoulding made is easy, does not allow easy damaged graphite inwall during the demoulding,
After the completion of sintering, mould inner wall is easily cleared up.Meanwhile for the mould, demoulding tooling is specially set, and the frock feature is：Adopt
With spiral pressuring method, product inner-outer sleeve is separated, applying power is stable, effectively avoids burn failure, reduces production cost, prolongs
Long die life, meanwhile, the demoulding tooling can improve demoulding efficiency, demoulding time be about normally stripped 50%, improve production
Efficiency.

Embodiment
Various embodiments of the present utility model are more fully described hereinafter with reference to accompanying drawing.The utility model provides
A kind of pressure sintering graphite jig and supporting stripper apparatus, including graphite jig and stripper apparatus, described stone
Black mould includes graphite inner sleeve 3 and graphite overcoat 2, and graphite overcoat 2 is arranged on the outside of graphite inner sleeve 3；Graphite inner sleeve 3 is cylindrical
Interior square, graphite overcoat 2 is annular；The graphite inner sleeve 3 is that two identical halfbodies combine, the graphite inner sleeve 3
Multiple cavities 5 are inside provided with, cavity 5 is built with sintered products, in the bottom of graphite inner sleeve 3, the lower end installation of lowermost end cavity 5
Graphite bolster plate 4, on the top of graphite inner sleeve 3, the top of cavity 5 of top is provided with seaming chuck 1, the shape of the seaming chuck 1 with
The shape of the cavity 5 of the top is identical..
Described stripper apparatus includes demoulding clamp 6 and knockout pin 7, and described knockout pin 7 is " work " font, and described is de-
The front end of tringle 7 is circular collar 71, and rear end is handle 72；The diameter dimension of circular collar 71 is not less than the diameter of seaming chuck 1
